Mi4s Cant Register On Network

[Nir Ma]

Hi all,
Brand new Mi4s which was bought in Shanghai.
I updated to Mi4S_multi_aqua_V7.2.5.0.LAJCNDA_v7-5.1-MiFlash (with MiFlash) and immediately after to xiaomi.eu_multi_MI4s_V7.5.2.0.LAJCNDE_v7-5.1 (with TWRP).
Somewhere in the process, I lost the ability to connect to the network.
Everything seems to be working fine, the SIM is recognized, but it does not register to the network nor able to manually find networks.
I tried to downgrade back to v.7.2.5 with MiFlash, but it did not help.
If anyone has any thoughts on the matter, please share!
thanks!
